It has two broad leaves and a single reddish to purplish brown flower with a callus of about six pairs of reddish to blackish glands covering two-thirds of the top of the labellum.

There are about twelve erect, linear, reddish to blackish glands on a wrinkled callus 4 mm (0.2 in) long covering two-thirds of the labellum near its base.

[2][3][4] Chiloglottis pluricallata was first formally described in 1991 by David Jones from a specimen collected at Point Lookout and the description was published in Australian Orchid Research.

[5] The specific epithet (pluricallata) is derived from the Latin words plurimus meaning "most"[6]: 540  and callus meaning "hard skin",[6]: 716  referring to the many glands on the labellum of this orchid.

[3] The clustered bird orchid grows in grassy forest in mountainous areas on Barringon Tops and the New England Tableland.
